THILL-COUPLING.

t SPECIFICATION forming part of vLetters Patent No. 276,580, dated May 1, 1883.

Application tiled January 30, 1883. (No model.)

To all whom it may concern Be it known that I, JOHN GROH, a citizen of the United States ot' America, residing at Shanesville, in the county ot' Tuscarawas and State of Ohio, have invented Tcertain new and useful Improvements in Shaft-Shackles; and I do hereby declare the following to be a full,

such 'as will enable others skilled in the art to which it appertains toA make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference specification.

This invention relates to improvements in shackles for shat'ts or poles in carriages, and has for its object to prevent rattling without the employment ot' rubber,as well as the easy and quick removal or attachment of the shafts or pole to the carriage. tained by the devices illustrated in the accompanying drawings, forming a part of this specication, in which Figure 1 is an elevation showing the parts applied to the axle of a carriage or buggy, and Fig. 2 a view partly in section.

The letter B represents a shaft or pole strap, of iron. H is a bolt, which passes through the end of it and enters the recess formed by the upper and lower part ot' the shackle4 when brought together, (indicated by the letters F F' in Fig. 2.)

A is `the upper" part ot' the shackle, having a semicircular recess, F, and provided with threaded portions A and A2, adapted to receive the nuts a a. It is shaped to fit snugly over the wooden and iron part of the axle-tree .and bind the two together.

C is the wooden axle-tree, and D the iron part of it.

E is a heavy plate of metal, having circular perforations Gr G', to receive the bolts A' A2, O and has a part projecting upwardly provided i These objects are att with a half-round recess, F', as shown in Fig. 2. The upper and the lower parts of the shackle are secured to each other by the bolts A' A2 and the nuts a a'. latter the two parts vmay be sufficiently separated without taking them entirely apart to introduce or to remove the bolt H from the recess F F', and in this manner attach or remove the shafts from the carriage. The bolt A2 and the uut a are elongated in order to allow of their being partially unscrewed, so as to admit oi' the removal or of the insertion of the bolt H ofthe shaft-iron B without entirely separating the couplings from the axle C D.

It is obvious that the shackle may be adjusted and tightened to any desired extent by the nuts a a', and thus be made to [it the bolt H in such manner that all rattling and noise will be obviated.

Having described my invention, what I desire to secure by Letters Patent and to claim 1s- 1. In a thill-couplng, the combination of the forked shaft-iron B, having bolt H, with strap A,vhaving semicircular recess F, elongated bolt A2 and short bolt A', and plate E, having semicircular reccssF' and circular openings G, substantially as described, and for the purposes set forth.

2. In a carriage-shackle or 'chill-coupling, the combination of forked shaft-strap B, having bolt H, adapted to be received between semicircular openings in strap A and plate E, and elongated screw-shank A2 and short shank A' with elongated nut a and short nut a', adapted to bind the whole together, as described, and for the purposes set forth.

In testimony whereofI atx my signature in presence of two witnesses.

' JOHN GROH.
